ENGINE-REPAIR STAND.

Application filed January 17, 1921. Serial No.'437,812.

To all to hem it may concern Be it known that we, Gnovnn C. LUoAs and MANNA M. PRATT, citizens of the United States, residing at Batavia, in the county of Jefferson and State of Iowa, have invented certain new and useful Improvements in Ijlngine-Repair Stands, of which the following is a specification.

This invention relates to an improved repair stand for motor vehicle engines and has as one of its principal objects to provide a device of this character wherein an engine may be supported in different convenient positions accessible for different particular work thereon.

The invention has as a further object to provide a stand having a swinginglyanounted supporting head and wherein said head may be moved to one position for sustaining an engine right sideup, may be moved to another position for sustaining the engine inverted, and may be moved to a third pos1- tion for sustaining the engine disposed horizontally.

And the invention has as a still further object to provide a device wherein an engine may be readily attached to or detached from the supporting head thereof.

Other and incidental objects will appear hereinafter.

In the drawings' Figure 1 is a perspective View of our improved repair stand,

Figure 2 is a detail perspectlve view of the supporting head of the stand,

Figure 3 is a side elevation showing an engine of conventional design supported right side up by the stand,

Figure 4; is an end elevation, particularly bringing out the manner in which the engine is attached to the supporting head employed, and

Figure 5 is a fragmentary end elevation showing the engine disposed horizontally.

In constructing our improved stand we employ pairs of diverging supporting legs 10. Between the upper ends of the legs of each pair is secured. a substantially triangular block 11 and connecting the pairs of legs are cross brace rods 12 while between the lower end portions of the legs of each pair is arranged a cross rod 13 upon which is rested a suitable supporting shelf 14 adapted to receive various tools or parts of the engine bein repaired. Extending between the upper end portions of corresponding legs at one side of the stand is a cross bar 15 and pivoted upon one of the legs at the opposite side of the frame is a rod 16 normally hanglng downwardly in inactive position. This rod is provided at its free'end with a hook 28 and slidable upon the rod is a spring pressed keeper comprising a sleeve 29 carrying a locking dog 30 normally extending across the hook.

Fitting through the blocks 11 is a cross rod 17 and mounted to swing upon said rod is a supporting head comprising a substantially U-shaped body bar 18 to which is secured a similarly shaped bracket bar 19 lying atsubstantially right angles to the body bar. The bracket. bar is provided with spaced openings 20 and secured to the lower ends of the bracket bar is a base bar 21 the end portions of which are curved laterally downward and are provided with reduced studs 22. v

In Figures 3, 4: and 5 of the drawings, we have shown the different positions in which our improved stand is adapted to support an engine, anengine of conventional design being illustrated, and in this connection it ma be observed that the device is particular y adapted for use in connection with engines commonly known as the Ford. The engine block is indicated at 23, the head at 24:, and the crank case at 25, the block and crank case being provided with Imating flanges 26 through which are engaged bolts 27 securing the crank case to the block.

In practice, a pair of the bolts 27 at one side of the engine are removed as is also the cylinder head outlet connection. The studs 22 of the base bar 21 of the supporting head of the stand are then fitted through the empty bolt holes of the flanges 26 of the en gine when a pair of bolts are, as particularly shown in Figures 3 and 4, fitted through the holes 20 of the bracket bar of the head and threaded into the bolt holes at opposite sides of the outlet orifice in the engine block. This done, the engine will be securely connected to the supporting head. Accordingly, the head may be swung to sustain the engine, as shown in Figure 3, at one side of the stand, when the cylinder head may be readily removed as may also the transmission cover so that access may be easily had to the valves for grinding the valves while also, access may be easily had to the transmission of the engine. By swinging the supporting head to lie at the opposhifted to rest upon the cross bar of the stand when the crank case may be readily removed, thus rendering the connecting rod bearings of the engine readily accessible as well as the main crank sha'lt bearings. In order that the operation of fitting the engine piston as well as tighteningthe bearings may be readily accomplished, the engine is, as shown inFigure 5, swung to a horizontal position. To sustain the engine in this position, the rod 16 is swung upwardly when,-

aiter retracting the sleeve 29, the hook 28 is engaged through one of the bolt holes of the base flange of the engine block from the outer side of said flange. The 'sleeveis then released when the dog 30 will be moved to confront the flange at its inner side for locking the hook engaged with the flange so that the engine will thus be rigidly held by the rod against movement in either one direction or the other. It will accordingly be seen that we provide a stand of'highly effective construction as well as a device which will greatly facilitate the task of properly and thoroughly repairing a motor vehicle engine.

Having thus described the invention,.what is claimed as new is:

1. An engine repair stand including'a stand body, an engine supporting head mounted to swing thereon and movable to lie at opposite sides of the stand body selectively, a rod pivoted upon the stand body and provided at its free end with a hook engageable through a bolt opening in the base flange of an engine upon the head 'for holding the eng ne in horizontal position sustained by the head, and a spring pressed keeper upon the rod to coact with said flange for locking the hook against disengagement therefrom.

2. An engine repair stand including a stand body, a cross rod carried thereby, a body bar mounted to swing upon said rod, a bracket bar secured tothe body bar, and a base bar carried by the bracket bar to form an engine supporting head.

3. An engine repair stand including a stand body, a cross rod carried thereby, a substantially U-shaped body bar mounted to swing upon said rod, a substantially U- shaped bracket bar secured to the body bar at substantially right angles thereto, and a base bar extendingbetween the free ends of the bracket bar to form an engine supporting head and provided at its ends with studs. i V

4. An engine repair stand including pairs of divergingsupporting legs, blocks clamped between the upper ends of the legs of said pairs rigidly spacing the legs at their upper ends and upstanding from the legs to form bearings, a cross rod journaled through said hearings, and an engine supporting head including a body bar journaled at its ends upon said rod adjacent the blocks forswingingly supporting the head. In testimony whereof we aflix our signatu-res.
